Cousteau is the granddaughter of Jacques-Yves Cousteau, a world-renowned explorer famous for recording his discoveries in books and documentaries, as well as pioneering the field of marine conservation. Jacques-Yves, together with Cousteau's father, Philippe Cousteau, produced "The Undersea World of Jacques Cousteau," an award-winning television series showcasing the wonders of the ocean.

Carrying on the family legacy of exploring and describing the natural world, Cousteau joined her parents on expeditions before she could walk. She has since traveled around the world, building her own legacy around water conservation and advocacy.

She is the founder of Blue Legacy International, a non-profit organization with the mission of empowering people to reclaim and restore the world's waters. Cousteau has produced more than 100 award-winning films for Blue Legacy, filming across six continents.

Cousteau has received a number of awards and honors for her work. She was honored in 2008 as a National Geographic Emerging Explorer, an award recognizing visionary young trailblazers who push the boundaries of discovery, adventure and global problem solving. The World Economic Forum also named her as one of its 2010 Young Global Leaders.

Cousteau and her family share their time between Washington, D.C., and Berlin, Germany.
